When an opponent's Spell/Trap Card, or monster effect, is activated that targets a "Frightfur" monster(s) you control: Negate the activation, and if you do, destroy that card, then you can send 1 of the targeted "Frightfur" monsters to the Graveyard, and if you do, Special Summon 1 Level 8 or higher "Frightfur" Fusion Monster from your Extra Deck. (This Special Summon is treated as a Fusion Summon.) During your next End Phase, banish the monster Special Summoned by this effect.
